Abstract
A non-penetrating mechanical fastener for securing a flexible sheet of an elastomeric material to the upper surface of a roof via the use of a plurality of such fasteners, each of which includes upper and lower members, wherein the latter are anchored to the roofing surface. The upper member includes an inner resilient retainer and an outer locking cap which clamp the sheet about an annular knob formed on the lower member. The locking cap is engaged by a compression fit with the resilient retainer to secure the retainer in position about the annular knob. A bolt and nut securely attaches the locking cap to the retainer to prevent their disengagement from the annular knob of the lower member. A method for securing the flexible sheet to the roofing substrate also is presented.
